A study of the relationship between concept emphasis in high school biology textbooks and achievement levels     

Hee-Hyung Cho  Jane Butler Kahle 《科学教学研究杂志》1984,21(7):725-733

A two part study investigated any relationship between student achievement and textbook content as well as any impact of a national project's recommendations on textbook content. First, analyses of student responses to biological items on the 1977 National Assessment of Educational Progress's survey of science showed a direct, linear relationship between achievement level and concept emphasis in biology textbooks. Second, a comparison between biology textbooks, published a decade apart, indicated significant changes in the degree of emphasis placed on 10 commonly accepted conceptual areas. Closer examination revealed that change in the amount of emphasis in one conceptual area, Growth and Development, was responsible for the significant difference found. Generally, the recommendations of the biology project were not reflected in the newer textbooks.  相似文献   

Identifying Interdisciplinary Research Collaboration in Instructional Technology     

Yonjoo Cho 《TechTrends》2017,61(1):46-52

Interdisciplinarity is defined as communication and collaboration across academic disciplines. The instructional technology (IT) field has claimed to have an interdisciplinary nature influenced by neighboring fields such as psychology, communication, and management. However, it has been difficult to find outstanding evidence of the field’s interdisciplinary research efforts, except with psychology. IT and neighboring fields including human performance technology, instructional design, learning sciences, human resource development, and human resource management share common goals of learning and performance in diverse contexts. These fields are converging in terms of underscoring the importance of people in improving organizational performance through learning, development, and innovations. In this context, the purpose of this study was to identify interdisciplinary research collaboration efforts in the field through a review of literature on the topic. Based on the review of the literature, I provided implications for research and practice.  相似文献   

Self-regulated learning: the role of motivation,emotion, and use of learning strategies in students’ learning experiences in a self-paced online mathematics course     

Moon-Heum Cho  Michele L. Heron 《Distance Education》2015,36(1):80-99

Enrollment in online remedial mathematics courses has increased in popularity in institutions of higher learning; however, students unskilled in self-regulated learning (SRL) find online remedial mathematics courses particularly challenging. We investigated the role of SRL, specifically motivation, emotion, and learning strategies, in students’ learning experiences in a remedial online mathematics course. With an online survey of 229 college students, we found that student motivation explained a small portion of variance in achievement; whereas student motivation and emotion explained a significant portion of variance in satisfaction. In addition, significant differences in motivation and emotion were found in passing and nonpassing students; however, learning strategies did not influence student achievement and satisfaction. Implications for teaching and learning in self-paced online remedial mathematics courses are discussed.  相似文献   

Managing knowledge performance: testing the components of a knowledge management system on organizational performance     

Taejun Cho  Russell Korte 《Asia Pacific Education Review》2014,15(2):313-327

The main purpose of the current study is to validate the framework of knowledge management (KM) capabilities created by Gold (Towards a theory of organizational knowledge management capabilities. Doctoral dissertation, University of North Carolina, Chapel Hill) 2001) in a study of South Korean companies. However, the original framework did not provide a thorough explanation of the effect of incentives, which motivate and encourage the knowledge management process. In this study, the modified framework that includes incentives in the knowledge infrastructure capability was tested. Moreover, since there is a weak linkage between KM and organizational performance, this study used empirical evidence to identify the relationship between KM capabilities (KMC) and four perspectives of organizational performance. Since structural equation modeling (SEM) is mostly used to describe causal relationships among unobserved (latent) and observed variables, this study used SEM procedures to determine whether there were any structural relationships between knowledge management capabilities and four perspectives of organizational performance. Moreover, the SEM procedure is “a statistical test to find whether a model fits a set of data, whether it matches a theoretical expectation” (Vogt, Dictionary of statistics & methodology. Sage Publications Inc., Thousand Oaks, CA, p 135, 2005). Therefore, this study also used SEM procedures to test a hypothesized model that had a good fit indicates that the model adequately describes the sample data. This study assumed that knowledge management capabilities could be divided into two types: knowledge infrastructure and process capabilities. The original hypothesized model showed that there was a positive relationship between knowledge management capabilities and organizational performance, but the overall model fit was insufficient to be accepted, because knowledge infrastructure and process capabilities were highly correlated. This study proposed two alternative models to find the best fit and found that knowledge infrastructure and process capabilities should be combined under the higher-order latent variable as subordinate latent variables. Lastly, there was a positive relationship between KMC and organizational performance. This study might not be free from common method bias to some degrees. It would be better to divide participants into two groups to respond to either the knowledge management capabilities survey or the organizational performance survey and to investigate the correlation between them. There are two main contributions for the field of knowledge management. First, this study attempted to integrate the fragmented literature of knowledge management into a holistic view and develop a framework for knowledge management. Moreover, this study found that there is a strong and positive relationship between KM infrastructure and process, which could refer that, to improve organizational performance, an organization should support KM processes, as well as build decent KM infrastructure. The results of this study would help KM practitioners to advocate the importance of KM to top managements.  相似文献   

How the Organizational Learning Process Mediates the Impact of Strategic Human Resource Management Practices on Performance in Korean Organizations     

Sei Hyoung Cho  Ji Hoon Song  Suk Chun Yun  Cheol Ki Lee 《Performance Improvement Quarterly》2013,25(4):23-42

The primary purpose of this research is to examine the structural relationships among several workplace‐related constructs, including strategic human resource management (HRM) practices, organizational learning processes, and performance improvement in the Korean business context. More specifically, the research examined the mediating effect of the organizational learning processes at three levels—individual, group, and organizational—to explain the relationship between strategic HRM practices and performance improvement. A total of 640 cases were used for data analysis, with general multivariate analyses and structural equation modeling. The results suggest that the learning processes at the three levels have a significant direct impact on organizational performance and that they also serve as a mediating interaction construct to maximize the effect of strategic HRM practices. The article provides conclusions, discusses the limitations of the research, and makes further recommendations.  相似文献
